For me it's this smilie: =.= Once in a while i find a smilie I really like and use it over and over. I tend to use them in my own way. I've kind of noticed this just now because I remember it was DX before and a long time ago I would use o.o all the time because it was so cute.
I can't think of any of my other obsessions.
But what about you? I mean temperary ones, not ones you have always obsessed over. I'm talking about well, sub-obsessions that you obsess over for a certain period of time and then get bored and discover another new obsession or whatever...if that makes sense?
